c# - Trying to install NuGet package programmatically - Package.GetGlobalService returns null -


i'm trying list of installed nuget packages in asp.net mvc application , i'm using nuget.visualstudio this:

var componentmodel = (icomponentmodel)package.getglobalservice(typeof(scomponentmodel)); ivspackageinstallerservices installerservices = componentmodel.getservice<ivspackageinstallerservices>(); if (!installerservices.ispackageinstalled(project, "templatebuilder")) {     var installer = componentmodel.getservice<ivspackageinstaller>();     installer.installpackage("all", project, "templatebuilder", (system.version)null, false); }

for reasons i've put above code in global.asax.cs file, componentmodel null. idea what's wrong it?

for reasons i've put above code in global.asax.cs file, componentmodel null. idea what's wrong it?

according icomponentmodel interface, can notice icomponentmodel interface in in microsoft.visualstudio.componentmodelhost.dll, visual studio sdk reference. if use icomponentmodel, need visual studio instance. generally, used in visual studio integrate project.

besides, when dig class ispackageinstalled:

bool ispackageinstalled(global::envdte.project project, string id);

you need pass parameter project, asp.net mvc project din't have project object. seems not use method in asp.net project in situation.

if want install nuget package programmatically, can refer how programmatically install nuget package? more detail info.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
